18 Efficiency on a large scale UNIVERSAL steam boiler ZFR series The UNIVERSAL steam boiler ZFR series is a shell boiler that uses patented 3-pass technology with two flame tubes as well as a completely separate smoke gas passage. The ZFR series is used when a high output of steam is required and ideally suited for a range of process-driven industries with high pressure requirements.

Efficiency on a large scale 19 Proven for decades and still pioneering The double-flame smoke tube boiler with separate smoke gas passages is suitable for operations that require only single firing. The 3-pass principle with a rear smoke gas reversing chamber that is held within the water chamber holds a Bosch patent. The economiser and superheater can be integrated easily due to its simple modular construction (ZFR-X steam boiler). The dimensions of the flame tubes, smoke tube bundles, water chamber and steam chamber are designed to provide optimum thermodynamics. Radiant and convection heating surfaces will generate a special dynamic in conjunction with the possibility of single-flame tube operation. The fed fuel heat is transferred evenly by means of flow components mounted on the water side of the steam boiler, and is then converted into steam without any thermal stress, thus contributing to system longevity. Efficiency optimising accessories The modulating output regulator for an 'unrestricted' single-flame or double-flame tube operation, and for continuous feed water control, is available as standard with the UNIVERSAL ZFR steam boiler. In order to achieve additional potential savings, we can offer you, subject to the system conditions, the following optional modules for increased efficiency: Variable speed burner fan O 2 controls CO controls Benefits at a glance: Intuitive boiler control High level of efficiency due to patented 3-pass technology, an integrated economiser and effective heat insulation Consistent high level of pressure and steam quality even with widely fluctuating steam demand Automatic start-up, standby and shutdown control Suitable for all burner systems Pollutant-minimised combustion with a highlydeveloped firing system and optimal matching of boiler and burner Simple to inspect on both the flue gas side as well as the water side for easy maintenance Robust, reliable and unsurpassed in its durability Compliant with the European Pressure Equipment Directive applied worldwide Wide control range thanks to its single-flame tube operation Simple extension options thanks to its integrated module technology spread capital investment Simple commissioning due to factory boiler control Easy wiring on site due to plug-in connections Technical data Type ZFR ZFR-X Heat transfer medium High pressure saturated steam High pressure superheated steam Design 3-pass double-flame tube/ smoke tube technology 3-pass double-flame tube/ smoke tube technology Capacity in kg/hour 18,000 up to 55,000 18,000 up to 55,000 Safety design overpressure in bar up to 30 up to 30 Max. flow temperature in C 235 300 Fuel Gas and oil Gas and oil

20 Efficiency on a large scale Construction Our patented 3-pass technology, dating back over 50 years, forms the basis for the outstanding and ongoing success of the UNIVERSAL ZFR series. Its suitability for the single or parallel operation of the firing units is due to both the stable separation on the flue gas side and the special design measures for neutralising the tension forces in single-flame operation. The flame tubes are pushed through and are welded tightly to the front and rear floors. The wet-back rear smoke gas reversing chamber is separated by a tube wall which is fastened to the rear floor and has water flowing through it. Water circulation and heat are efficiently transported by means of guide profiles on the boiler base, and are additionally accelerated by the flow gases between the flame tubes and the smoke tube areas alongside one another. Flexibility in operation A fully automatic operation with one or both burners is made possible without any restrictions due to the approved single-flame operation. Different fuels in both firing units do not present any barriers. The control range is doubled and each low load phase is run with one burner to provide an improved efficiency level. High pressure superheated steam For applications where superheated steam is necessary instead of saturated steam. A superheater module can be placed on the front reversing chamber, resulting in an upgrade to the ZFR-X steam boiler and a bypass flap constantly controls the temperature of the superheated steam over a large load range. The smoke tube areas remain easily accessible. Modular system controlled on the flue gas side no injection water required for temperature control of the superheated steam Easy maintenance and installation simple cleaning with the second and third boiler pass Extensive product life low thermal stress on the heat exchanger Manufacturing comprehensive and bespoke All Bosch UNIVERSAL steam boilers can be delivered complete as a fully-functioning unit. The basic equipment level supplied by Bosch includes a boiler pressure vessel, control and safety technology, burner unit, pump module, terminal box and the control switchgear cabinet including our easily operated boiler control.
